Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509926, here are decompositions:

5 + 509921 = 509926
17 + 509909 = 509926
47 + 509879 = 509926
59 + 509867 = 509926
83 + 509843 = 509926
89 + 509837 = 509926
227 + 509699 = 509926
233 + 509693 = 509926

Showing the first eight; more decompositions exist.
